| Résumé : |
Salt tolerant halophyte Sesuvium portulacastrum (S. portulacastrum) is capable of absorbing sodium chloride. In the present study, the feasibility of using S. portulacastrum as a bioaccumulant for NaCl present in tannery wastewater has been studied. The plants were grown in soil fed with tannery wastewater with varying concentrations of NaCl. The growth parameters of the plants such as root and shoot length was studied. The amount of Na+ and Cl- accumulated by the plant in leaves and shoots were estimated. The accumulation of Na+ and Cl- increased with increase in plant density and salt concentration of tannery wastewater. However, it has been found that increase in salt concentration resulted in reduced growth of the plant. It has been observed that 34% of Na+ and 22% of Cl- were absorbed by the plant at a NaCl concentration of 15000 ppm at high plant density conditions. Maximum accumulation of Na+ and Cl- has been observed in leaves compared to stems and shoots. The results of the present work indicate that S. portulacastrum can be used for bioaccumulation of sodium chloride. |
